Obligations on the country to monitor their

companies overseas were removed

Developed nations need to stabilize their

emissions at 1990 level only by 2000

Rich Western nations were absolved from the

guilt of overconsumption of the world’s resources

All nations agreed that, the target of cutting

greenhouse gases was meaningless unless there were some ways of achieving it

It was due to the collision of two oil tankers

Prestige and Erika

It was not an accident; but an experiment that

went wrong

It was an accident involving Nakhodka (a Russian

tanker).

Inertness and stability of CFCs facilitate the depletion

of ozone layer

According to the Montreal protocol, countries

producing ODS > 300 mg/capita/year need to fund the fight against the O

depletion

CFCs were one of the most useful class of

compounds ever developed because of their chemical stability,

non-inflammability, non-corrosiveness and low toxicity.

CFCs were developed as a safe alternative to

Freon-11

generated during combustion is

exiting at a very high temperature

generated during combustion

contains large amount of water vapour

generated during combustion is

diluted with Nitrogen.

generated during combustion is

polluted with CO and particulate matter

Exchange of heat between the water and the air

will take place in the ocean.

Salt or mineral content of water is much larger

than that of the air.

Specific heat of water is much larger than that

of the air.

Specific gravity of water is much larger than

that of the air.

locked at the ocean bed at

They will reach the stratosphere, but they

contain H atoms that reduce the molecular weight of the compound and they go

further up above the stratosphere

They

will not reach the stratosphere as they contain H atoms which react with the

oxygen of the lower atmosphere.

They will not reach the stratosphere as they

contain H atoms which react with the hydroxyl radicals of the lower atmosphere

They will reach the stratosphere, but they contain H atoms which react with the

chlorine atoms of the stratosphere. Hence, chlorine will not react with Ozone

This is practically not possible as these

organisms cannot multiply due to the non-availability of oxygen due to red

tides

This is practically not possible due to the turbulence

in the ocean that might disperse the organisms applied.

This is economically not viable due to the huge

cost involved in the culturing of these organisms

This is environmentally not viable as these

organisms might multiply beyond control and might create problems
